TPS63070: Not functioning, gives no output

Part Number: TPS63070

Hello,

We are using TPS63070 Buck Boost regulator in our application. PFA Buck Boost section of our application.

We are giving 9-15 V as Input and we want 5V as output.

The enable pin is dynamically controlled to ON/OFF the regulator.

The Buck Boost does not start even after giving high to the ENABLE pin of the regulator.

When the ENABLE pin is given high the TPS63070 reaches a maximum of 0.59 V and does not give the desired 5V.

Please advice the reason why it could be and the solution for it.

Thanks,

Ameya

Hi Ameya:

May I check your system information first? Is there any load in your circuit during the test? What's the power supply and the value of the current during your test?

It's better to catch the waveform of Vin, Vout, L1, L2,En. Thank you~
